“some” >>>>>>>>>>>>>>>
Go ahead and leak some documents so gaijin can model your NERA armor(joke). It’s not easy to model such things. Gaijin doesnt have the exact specifications of these armours.
Gaijin doesn’t need to learn new information to change how round penetration mechanics function. There are already two mechanics ingame which reduce spall, fuel tanks and spall liners.
NERA armor should be treated the exact same way as this is how it works in real life. A reduction of spall, less penetration due to the effect of the armor on the round. They do not need armor specific make ups they just need to fudge the numbers and have a reduction by a percentage to offer “realism”.
You still don’t understand. NERA isn’t a magical material that reduces “spall”. It reduces overall penetration by breaking up the penetrator as opposed to just stopping one by heaping up sheer mass as in a solid plate. That is just the mechanism by which it functions. Its used because mass for mass it produces greater resistance, at the costs of far larger volume.
But.
If a NERA array is overmatched by a projectile, it is going to produce as much behind armor effects (“spall”) as an equivalent solid plate or even composite.

Do you have for a source on this?..
I am unaware of any NERA which isn’t by definition also a composite.
NERA doesn’t necessarily break up the penetrator. It works by dissipating the energy over a larger area, exploiting the refraction of the shockwave as it transitions between different materials in the composite sandwich.
A NERA block which gives the equivalent protection of say 200mm rolled-homogenous steel, would be much lighter than the steel plate. It would literally defy the laws of physics for it to generate the exact same amount of spalling - there isn’t enough mass there.
Like most things in this game, GJN can’t be bothered to properly implement NERA given that Russia doesn’t really use it or stand to benefit from it in game.
NERA also integrates softer, non-spalling materials such as rubber, plastic or polycarbonates that would catch spall from penetrated steel plates.

NERA is outside hte “normal” armour isn’t it?
So there’s no spall until it has penetrated the armour BEHIND the NERA - which is jsut steel (usually) and so produces spall jsut like any other steel.
- Too much “cost” to caculate like i said, even a nearly penetrated shot still causes spalling but in the case of “real time caculating”, the math should be simplify the output to “yes or no” (in this case, pened or not).
- About the tank rounds with special mechanic like anti era tip, with the current method that Gaijin is using (an algrothrim, not based on a report of how much it penned) and ammo model should be based on armor model, the ERA they modeled is likely recycle rom “tracks armor” but much worse “endurance”, improvise base on what you got is good if that the case Gaijin used, i’m understand for that decesion, much more time to caculate ( → so no real time since you have to wait longer for the compute to caculate and tranfser it) it’s just add more job to the hardwares (which is heavily costed since the latest revamped game engines).
- Programming is hard, especialy for an online game, choosing and balancing between “efficiency” and “features” also hard, you need to made a choice between it, more popular (because it’s lighter) or more realistic (but also less player since the hardware requirment is also higher).
NERA and ERA are the same but with different approach to achive the affect of breaking the trajectory of the round and blunt the tips (for APFSDS) and both try to get the “Reactive effect”.
The concept of them is trying to move two differnt plate opposite each other (to defeat something moving, you also need to move) using a filler between two layer/plates:
- ERA uses explosive between 2 plates/layer, the explosive also need to be precisely caculated.
- NERA uses high resilient material like rubber but later, something else i don’t know since it’s classified.
Both Soviet tanks like the T-72B/64B/80U used NERA too.
Composite is a term to describe a multiple layer of different material to achive something, in this case is the “Reactive Armor’s effect”, not to distingush between them.

thats the case for most tanks iirc only the leopard 2 mantlet actually generates spall in game
That is composite comprising of plates and NERA elements.
That is a more intricate composite, also comprising of NERA elements.
NERA very often has gaps in the armor, as seen on the Leopard, Leclerc, T-72/90/80. This isn’t what defines a composite array, and you shouldn’t base an entire classification on “gaps”.
Most composites with gaps comprise of “reflecting plates” or “spacers”, both normally having NERA elements. Both are found on the Abrams, and each plate is backed by NERA materials.

Nera its a sandwich of steel and rubber and due to the properties of rubber it tends to eat the spall irl aswell as its not thick enough to cause too much spall, this dosent mean it eats spall like a spall liner of course dont miss interpret this
Irony.
NERA is not properly modeled in the end its missing a lot of its actual capacities
Such as?
